@Leblond Yes, there is a way to detect motor stalls. See https://duet3d.dozuki.com/Wiki/Stall_detection_and_sensorless_homing#main

Leblond

@chrishamm ok thanks, I print it and I care about it

Good morning and good May 1st
Well I have a problem that repeats itself every time I homing, then I thought the last problem had been the fault of the nozzle blocked by the filament, in part yes, it blocked because the extruder motor stops, now I understood the reason, the tests I did are all without filament in order not to damage the nozzle, I describe what I did:
1: I set the temperature to 180 in order to have the extrusion and retraction buttons active the drive buttons work very well and the motor responds
2: if I homing all the axes and retry the procedure n.1 the extruder no longer works
3: I did the single homing of the axes
4: homing x axis and retrying the extruder and it works
5: homing y axis and retrying the extruder and it works
6: z axis homing and try again the extruder does not work
I tried to load the fw one by one starting from 3.0 until the last beta and the problem persists,
7: I removed the sd and reformatted and loaded the fw but nothing happens
Any suggestions on this?

now I have mounted the fw 2.05 to see if even with this it does the same problem

dc42

Is the tool still selected when you have this problem? Send T by itself to report the current tool number.

Leblond

@dc42 ok I reassemble the FW and then I tell you

Leblond

@dc42 made reloaded FW 3.01-RC10
yes the tool is always active

Tool 0 is selected

Leblond

@dc42 I compress all the sd and send it to you?

Leblond

it still does not work

Leblond

the engine practically vibrates as if it were stalled

Leblond

@dc42 I confirm that with version 3 of the fw I have this problem, but with the version of FW 2.05 everything works great, so I will continue to use FW 2.05, until you can understand where the problem lies

Leblond

Hi everyone, have you discovered anything about my problem?

Leblond

good morning guys
I have found that by sending the axes home manually one at a time starting with x, y and z, the extruder works

Leblond

but as soon as a g28 is made it no longer works and the extruder stalls

Leblond

I also installed Release 3.01-RC12 ma niet

Leblond

for @dc42 no idea?

Leblond

Guys forgive me if I insist, but it seems strange to me that only I have a problem with a brand new card and you can't find a solution
